RS485 Three Phase Fee Control Electric Energy Meter for Nation Smart Grid
Description:
RS485 Three Phase Fee Control Electric Energy Meter is a smart metering device with special design for nation smart grid. The meter has advantages of high accuracy, good linearity, wider range and long life, which can widely used in city, country or school and any enterprise.
Features:
1. Product's Type: Remote, Remote Carrier, Local, Local Carrier.
2. Electric Power Measurement: Positive/reverse active power, positive/reverse apparent power, reactive power in 1,2,3,4 phase and active/reverse power in A, B, C phase which can be measured.
3. Muti Tariff: It can set for 2 time zones, 2 programs of daily time and swiching time (yy/mm/dd/hh/mm) of these two.
4. Demand Measuring: It can measure max demand and the time when it occurred for positive/reverse active power, positive/reverse apparent power, reactive power in 1,2,3,4 phase, reactive group 1 and 2.
5. Event Log: With function for logging events such as clear, program, timing, power downn, switch out, switch on, open meter cover and etc.
6. Communication Mode: Infrared + RS485 interface, carrier communication module, wireless GPRS/GSM, CDMA is optional.
7. Maximum Demand Measurement:
Measure total and time-sharing reverse active &reactive maximum demand and time of occurred.
Measure total and time-sharing reverse active &reactive maximum demand and time of occurred.
